Exercise - Burning 6000 calories a week

Hi guys
I would like to create a calorie deficit primarily through exercise. Any suggestions for what exercise I can do and frequency to achieve this?
I haven't exercised since before the pandemic but when i did: i loved strength training, despised cardio with a passion (although i will do it to keep my heart healthy). I have a dodgy knee so prefer to avoid too much jumping or long distance running. Don't mind exercise classes such as spinning, body pump, boxercise or hot yoga. I don't swim.
If it helps, i have access to a gym and a personal trainer.
Thank you to anyone who takes the time to reply!

6000 calories a week, for most people, is around 12 hours of decently hard exercising a week.
I burn around that, but it takes me 7 pretty brutally hard sessions by most standards. I do cardio 6 times a week and lift 2 X a week. One is where I lift and use a rowing machine doing HIIT for an hour. I've been training for 15 years to get to the point of burning that many calories in 7 or so workouts a week.
IMHO, saying I'm going to burn 6000 calories a week to lose weight is setting yourself up for failure. If you tried to do 6000 calories this week in exercise and you haven't exercised since Covid, you're going to likely injure yourself.
Why not ease back into it? The only way I could possibly burn 6000 calories in a week is because I spent 10 years very, very slowly (incrementally) easing my way into more exercise. And I'm consistent as hell. When I started jogging (and that's being kind with what I did), it used to take me an hour to burn 400 calories. I regularly burn 650 to 750 or 800 now on my "easy" days. But understand, that takes years to develop that kind of cardio stamina.
I have a very dodgy knee too. Was told 16 years ago I needed a full replacement. Rowing is easy on the knee. So is stationary bike and (some) ellipticals -- ellipticals can hurt my knee too. Climbers are great. So are Stairmasters.
If you really want to burn calories, start slow -- build back gently. Don't go too hard or you'll get discouraged and quit.9 -
It sounds like you are trying to lose 2 lbs. a week without changing your diet. That is very rapid weight loss unless you are more than 50 lbs. overweight and not easy to sustain. I think you overestimate the burn you get with exercise. Weights don't burn many calories. Nor does yoga. Cardio does burn more calories, but is hard for a beginner to do for long enough to burn significant calories. For me to burn 1000 calories a day, (assuming one day of rest each week) would require 10 miles a day of running or 20 miles a day hiking or 3+ hours a day on the stationary bike. Low impact aerobics would require at least 2 hours a day, probably more. That is a lot of exercise. I've been running and walking daily for years and I wouldn't want to do it.
And one issue I've found with using exercise as a primary means of weight loss is that when you get injured (and odds are, you will get injured if you push yourself that hard) you haven't developed eating habits that will allow you to maintain the weight loss without the exercise, so you quickly gain back the weight you lost (and then some). You would do better to focus on cutting your calories and increase your exercise gradually to a level that is sustainable so that the exercise allows you to eat a few more calories but isn't necessary to keep the weight off.5 -
Really not enough info about your history to give the advice you probably want but from what you stated...
I would resistance train with appropriate intensity, volume, and rep ranges. If your knee is "dodgy" because of recent trauma, I would seek medical advice. If you claim it is "dodgy" for any other reason, I would want more info as these are usual remedied with appropriate training by a experienced trainer, more than likely not a commercial gym trainer who unfortunately don't have the experience or knowledge for optimal results if any.
If you want to goal 6000 calories burned a week, I would highly recommend you not start anywhere near that level since you have been inactive for a long time.
I would strongly recommend utilizing proper load management as without it your injury risk increases substantially. I'm not trying to alarm you, but it's a mistake I see time and time again.
Feel free to add me as a friend. I'm not extremely social here anymore, but my page will be focused on a day or so to answer questions that you have for a professional experience coach, trainer, and athlete.3 -
Something not mentioned yet is that adding exercise into your routine can easily increase appetite. I personally am much more hungry days I train than days I don't. Managing to avoid eating more is going to take almost as much discipline as it will take to add that much exercise.6

The classes you mention really aren't big calorie burners - they are also difficult to get somewhat reliable estimates for but very easy to get highly inflated ones!
Strength training is also a small calorie burner (but a very valuable use of exercise time especially when losing weight).
Overall the gym really isn't the place to burn that kind of number unless you have extraordinary determination and resistance to boredom.
If you are serious about building up to 6,000 exercise cals a week and have a dodgy knee (whatever that means) then cycling is the pretty obvious choice but depending on where you live if it's winter roughly 12 - 14 hours (guessing your future and not current fitness level here) may not be easy (or enjoyable).
Realistically I think you are not going to achieve that number consistently.
For comparison I've done 377 hours / 5,600 miles this year cycling and that's only just over an average of eight hours a week but I'm retired with lots of time to indulge my hobby and also eating at maintenance. I couldn't sustain that level of exercise and have a large calorie deficit for more than a few weeks.
I think if you want to eat at maintenance and use exercise to create a moderate deficit that is workable but I really don't think your plan will work without scaling back - a lot. Sorry!

Not to burst your bubble, but I think you are substantially underestimating the level of time and effort it would take to burn 6000 calories per week and to do so on a consistent, regular basis. Also, as you've not been exercising for a couple of years, your current fitness level would be nowhere near where it would need to be for this kind of training. None of the things you mention are particularly big calorie burners...you would need to do a ton of cardiovascular work to achieve 6000 calories per week...probably in the 12 hours per week range every single week. Even when I was training for endurance cycling races and events and spending gobs of time wracking up the miles, I wasn't anywhere near 6000 calories per week. You also need to consider that life happens and injury happens.6 -
Well, if you have access to a personal trainer s/he would be my first port of call.
That said, burning 6k calories per week through exercise is a really tough ask.
My TDEE per day is 2300. I am a 5'10" female weighing 75kg. I exercise every day. A tough weight lifting session 4 times per week for an hour (plus another 45 mins or so spent on warm up, cool down and mobility work). I do 45 mins of boxing pad work with a PT once a week, 45 mins of general conditioning work once a week and the seventh day is normally high intensity cardio on the heavy bag for between 30 and 45 mins followed by mid intensity cardio like kettlebells or rowing for another 30 mins. As you can see, I spend a fair bit of time exercising, and my height and weight mean I burn a reasonable amount of calories. All of that said, my exercise burns on average 400 calories per day, so nowhere near 6,000 calories per week.5 -
OP, the folks who've responded have made some great suggestions while also giving you the "unvarnished truth".
While it is possible to burn 6000 calories/week, that is not a plan that is sustainable nor advisable for anyone who doesn't have a significant base built up. @Mike Pfirrman's response makes this point nicely. In a best case scenario, you get discouraged and quit, while a worst case outcome is injury. In either of those cases, you will suffer during the process.
Since most brief duration cardio classes would not generate the calorie burn you seek, then the alternative approach requires a lot of time. As @sijomial suggests, long distance cycling could provide a path to larger calorie expenditure, but that isn't an easy task. Eight hours of cycling time weekly is not where beginners start, and even as your fitness grows, so will your hunger.
Finally, I'll give you my specific calorie burns from two different weeks this past summer to illustrate the time commitment. (BTW, my focus is endurance, not weight loss)
Week of July 19-25, Total training time: 11hrs, 18min. Calories burned: 3047 on bike, 1681 on run, 848 during swim. Total: 5576 calories.
Week of Aug 9-15, Total training time: 14hrs, 15min. Calories burned: 4104 on bike, 1006 on run, 755 during swim. Total: 5865 calories.
So my two cents is that a focus on food intake, coupled with a moderate exercise program to start, will lead to an exercise habit that supports weight loss while improving your fitness. Good luck.

I'll second that.
Basically, you'll be pretty hungry and it'll be really hard to resist eating back a big chunk of those exercise calories. Without a (superhuman?) discipline, you'll get used to eating a lot. And then, when you don't exercise as much, while still eating the amount you've gotten used to, well, we know what'll happen.
Been there done that (and still doing that).
Oh 6000 calories is a looooong time exercising and it's not easy in the long run. Trust me 😁0 -
Thank you everyone for your kind comments. I asked for your advice so I am going to take it and go easy on the workouts to avoid burnout or injury!5

Turns out I vastly underestimated the amount of calories one can burn while exercising!! I’ll definitely start slow as suggested.
I actually love rowing intervals so I’ll incorporate those. Thank you.

You got really good advice, and you took it to heart. Things don't usually work so well here. For what it's worth, the kind of person who's able to learn from a disappointing truth (about how many calories are being burned, or other things) is usually the kind of person who has what it takes to be successful.6

Yes the goal is 2lbs a week. I have a slow metabolism for various reasons which means that I find it difficult to lose weight by reducing calories. I started at 200lbs and have so far managed to lose 8lbs at a snail’s pace. I’m aiming for a total loss of 50 lbs to get me to my pre-pandemic weight so there’s a lot to go.
You have made a very good point about injury. I will focus on slowly building up my exercise as suggested and see how that goes.

Thank you for the advice and I will take you up on the offer to add you as a friend.
I think the dodgy knee might be to do with me being too heavy when it comes to jumping/running type activities and improper form when it comes to things like lunges.
I have actually struggled to find a trainer this time round as they seem to be inexperienced and, based on appearances only (which i am aware is not always the right approach) don't seem to follow their own training plans.0 -
Lots of great comments and advice here. Good luck, the only input I'll add is dont beat yourself up if you have an off day or even week, just reset your head and motivation then get back on it

you cant out exercise a bad diet.
losing weight through exercise alone IS possible, but IS difficult (not to mention, as others have said, your hunger levels will increase), and then you run into the problem of MAINTAINING that loss....
What happens if you injure yourself, or have a health issue and can not work out, or for any other reason can't workout? what then? I wasn't able to work out for the majority of this year. Doctors orders. I have a slow metabolism (due to significant weight loss). I still lost 50 pounds this year on diet alone. So.... a slow metabolism is no excuse for diet not working.
Just some things to think about, that sometimes we dont ....1 -

If you do choose rowing, look closely as some rowing instuctions online. Dark Horse Rowing and Cassie Neimann are two of my favorites. I also saw you in the UK. There are a TON of rowing gyms and rowing clubs there. On the water rowing there is huge. I'm a member of an online (indoor) rowing club and nearly 70 percent of the members are from the UK. Rowing is one of those things that's not really intuitive. It seems like it is but it so isn't. If you start out with good form, it's much easier.
Don't give up on cardio just yet. I detested cardio when I started losing weight. I started out just walking and using stationary bike and light lifting -- simply as a means to get more calories to do my favorite thing -- eat!
A fantastic approach to exercise is just eat your calorie budget and use exercise as a cushion for weight loss and measuring mistakes. I used to try to eat back some of my exercise calories, but not all of them. Like half of them. What I found, over time, is because I became so consistent, I enjoyed pushing the cardio after a few years.
Now, I'm "one of those guys" that does cardio and is somewhat addicted to it. I get really cranky now when I don't do cardio. I enjoy weights too but not as much. But a great routine includes both and even (perhaps) some flexibility exercises as well.
While everyone is right that weight loss is primarily in the kitchen, I will tell you that maintenance is where exercise habits become more critical. Nearly everyone I know on here that is years into maintenance also exercises a lot. The National Weight Loss Registry (which is for people that have lost over 100 lbs and kept it off for years) did a survey a while back and what they figured out was the average time people spend exercising, who have kept weight loss off for years (and that number is only like 10% of people that drop the weight keep it off), is an hour a day. I lost around 100 lbs originally, so that's a number I shoot for -- roughly 6 or 7 hours a week. But that has to be something you organically build up to while being smart.2 -

I’m in the UK but sadly nowhere near the water. Thank you for the pointer towards rowing videos - I’ll check them out and use until I find a decent trainer. My last trainer (in London) was a rowing enthusiast and after a year of rowing and generally working out with him I didn’t suffer any injuries. I miss him!
Interesting study. Exercise is very important for me too and also because it allows me to eat more and maintain once I get to goal weight!

what makes you think you have a slow metabolism?
15 years of yo yo dieting and, lately, limited exercise! I have actually been limiting my calories - I eat between 1200 and 1400 calories and still struggle to lose weight. I count all calories so I’m certain that is the range I fall into. I cannot further reduce my calories so exercise makes sense to boost my metabolism and lose weight.0 -
You are pretty near the Thames, there's quite a few rowing clubs if you fancy on the water.
(I'm a bit further upstream near Hampton Court and would be spoiled for choice if it were my thing.)2 -
The only thing I can add is you ought to get to the root of your balky knee problem either through a doctor, trainer or both. I’d want to know if it is truly a problem that could get worse through exercise or something minor, ie muscle imbalance, tightness or something else that can be improved or eliminated through appropriate stretching and exercise.
Edit: I see that the above issue was raised so I’ll just second looking into it.1 -
To get that much, it would have to be somewhat low intensity cardio that you'd be able to do frequently for long durations. Running/jogging would definitely not work - it would take possibly years to work up to that kind of volume. Cycling (150-200 ish miles per week) would possibly be the most viable option...but you'd definitely still want to work up to that.1

Just thought i would post an update - i had my first personal training session in about 5 years today (add general idleness, a baby, pandemic and 50 lbs in that period) and after an hour of a workout hard enough to make me throw up (literally) according to my Fitbit i burned 350 calories. The workout mainly involved weightlifting but was hard enough to make me seriously sweat. Needless to say, i will not be burning 6000 cals a week from exercise anytime soon

A journey of a thousand miles (or calories) begins with a single step.
I know exercising can be pretty hard in the beginning but eventually you will feel better and better! Keep going.5 -
Congrats on starting your program! Calorie burn doesn't really matter too much as you get underway.
The only thing that really matters is not stopping until exercise becomes a habit. So just make a decision not to stop. The physical benefits and sense of well being you'll get from regular exercise are worth every minute spent doing it.3 -

And as a couple comments mentioned regarding calorie burns from lifting - HR-based calorie burn calculations (like Fitbit is doing) are ONLY a valid estimate (and even then with caveats) for steady-state aerobic exercise.
Your workout was totally opposite - anaerobic if lifting and done right, HR up and down constantly.
So even that 350 given calorie burn was inflated - probably closer to 200-250.
You've really setup impossible parameters to reach your goal as you seem to recognize now.
Sweating means you were hot, nothing to do with calorie burn or even intensity - but good job. Though if to puking stage you may need a bit of recovery now. So a workout tomorrow may not go so well or as intense.
While 2lbs weekly loss rate could be reasonable for MORE than 50 lbs to lose - it also depends on what stress your body is under.
If under 50 lbs - than 2 lbs no longer reasonable but more likely extreme - body doesn't like extremes - it'll adapt.
And if you have illness body is dealing with, even a slower rate may be needed.
How much left to healthy weight?
Very few people actually have a slow metabolism more than 5% under calculated, even with thyroid problems. That effect is just being tired and moving less, not base metabolism.
And exercise isn't going to increase that metabolism much at all. Unless you mean something else by metabolism.

Did you literally vomit? (Rhetorical question, you don't need to answer.) If you did vomit, was your trainer OK with that? IMO s/he shouldn't be! Vomiting generally is not good for you, and you want to avoid frequent repeats.
If that's happening, loosely a couple of things could be in play (and maybe some others I'm not thinking of right now).
One is timing of eating around the workout. Some people find that if they eat (a particular volume, or particular foods, or just anything) close to a workout, then digestive consequences happen. On the flip side, being super empty/hungry (or seriously under-hydrated) can potentially do the same thing. Consider that, and experiment/adjust. People differ, so I can't be more specific.
Another is physiologic consequences of the exercise intensity or total cumulative stress (from the physiology of the exercise, but potentially augmented by other stressors in the situation). Again, it's somewhat individualized . . . which is not to say there's anything wrong with the *people* who experience those consequences! What's wrong is the circumstances/outcome, and the training needs to be adjusted accordingly.
I don't want to get too speculative, but things like lactate tolerance might be in the picture. Also, warming up gradually may be helpful.
I do a sport (and earned coaching certs in it) in which vomiting at competitions (or extreme training sessions) can occur. There are trash cans strategically placed at major competitions just in case. However, routinely vomiting is Not A Good Thing. I can't diagnose you over the internet, but if it's happening for you because of exercise intensity, very generally find the edge, and work *sometimes* manageably close to that edge - not *always* close to it - and that can help move the threshold. As a baseline, use stress management techniques (breathing, etc.) if feasible to reduce the non-exercise-specific stress component.
You should not be vomiting workout after workout. NotNotNot.4 -
Agree with Ann. You sound a lot like my wife -- full steam ahead, has to back off, gets injured, full steam ahead, gets discouraged and quits, back at it harder, repeat insanity...
Consistent, gradual, incremental improvements in fitness are the best way. Sustainability is so important.
Out of curiosity, I ran my weekly exercise calorie numbers up. I did 4950 last week. I literally started after a knee injury around 15 years ago (I was an athlete in my youth but took around 20 years off of being physically active outside of a job). I couldn't walk at that time and started out with just a few revolutions on a Stationary Bike and working up to walking again -- sometimes just a few steps -- later into a few hundred steps.
I can't overemphasize enough that you should do only what you can without too much pain or soreness (or vomiting) and just be super consistent. If I can come as far as I have, you can too. You're way ahead of me now, just slow down and stay safe!0
